Pitches in Brittany/Europe

Hi

We're thinking of travelling to Brittany in the late spring 2013 and wondered if the pitches on the sites there are similar to the CC sites in the UK.  IE large enough for van, (24ft), afull wning and car.  Also are there any major differences we should be prepared for.  Any advice would be greatly appreciated along with site recommendations please.

Cheers
